Registrants of the same substance must be part of the same registration

As of 27 January, you will no longer be able to submit a registration dossier separately if a registration for the same substance already exists. Similarly, you will not be able to update your registration, which has been submitted individually, if another registration for the same substance exists in REACH-IT. If your registration is not in line with the joint submission obligation, it will be rejected at the ‘business rules’ step of your REACH-IT submission and you will be instructed to co-operate with the existing registrants of the same substance and submit jointly. This means that you need to discuss with other companies about substance sameness, share data and costs with them and, subsequently, submit your registration as part of a joint submission. ECHA guidance documents and other support material reflecting the changes are under revision. Further information is available at: Commission Implementing Regulation (EU) 2016/9 of 5 January 2016 on joint submission of data and data-sharing(EurLex)
